The softening point temperature of quartz glass is about 1730°C. It can be used for a long time at 1100°C, and the maximum temperature for a short time can be up to 1450°C. In addition to hydrofluoric acid, quartz glass almost no chemical reaction with other acids, and its acid resistance is 30 times that of ceramics, 150 times that of stainless steel, especially at high temperatures, the chemical stability of any other engineering materials are incomparable. The thermal expansion coefficient of quartz glass is extremely small, can withstand drastic temperature changes, the quartz glass will be heated to about 1100 ℃, into the room temperature water will not blow up.

Large Diameter Glass Tube can be used in roof lighting and ventilation systems to effectively utilize natural lighting and ventilation to save energy. It can bring natural light into the room, reducing artificial lighting, while reflecting solar radiation during the hot summer months to avoid heat buildup. In greenhouse construction, large diameter glass tubes can improve the utilization efficiency of surface radiation in greenhouses due to its high light transmission performance, which promotes the growth of plants and isolates external pests and viruses to safeguard the quality of crops.
